Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: One-arm research group
Drug: Serplulimab Combined With FOLFIRI and Bevacizumab
For patients with confirmed failure to reach CC0/1, they should be treated with sullizumab combined with FOLFIRI+bevacizumab for 4-8 cycles within 3 weeks after the exploration operation. After the end of the 4th and 8th cycles, they should be evaluated with imaging and MDT. If the conversion is successful, they should be treated with a second exploration operation within 3-4 weeks, The patients with CC0/1 can be evaluated for tumor reduction surgery (CRS) combined with intraperitoneal hyperthermic perfusion chemotherapy (HIPEC), and the follow-up treatment plan will be selected according to the clinical situation of the patients after surgery; If CC0/1 cannot be evaluated after the second exploration surgery and CC0/1 cannot be performed after the imaging evaluation, other chemotherapy and optimal supportive treatment will be performed according to the situation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Disease-free survival (DFS)
Time Frame: 3 years
The period from the beginning of treatment to the first occurrence of disease progression or death from any cause. If such situation is not met, the last evaluation date shall be used for analysis. In addition, if the treatment is terminated without confirming the progress of the disease, the imaging examination and follow-up should also be carried out after the treatment is terminated.
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Objective Remission Rate (ORR)
Time Frame: 3 months after preoperative chemotherapy
The proportion of patients whose tumor volume has shrunk to a predetermined value and can maintain the minimum time limit. The remission period usually refers to the period from the beginning of curative effect to the confirmation of tumor progression. The objective response rate is generally defined as the sum of complete response plus partial response (CR+PR).
3 months after preoperative chemotherapy
3-year overall survival (OS)
Time Frame: 3 years
The time from the date of treatment to the date of death due to any reason. For patients who survived in the final analysis, the date of the last contact will be recorded.
3 years
CC0/1 resection rate
Time Frame: during operation
Complete tumor reduction surgery: CC-0: no peritoneal residual tumor; CC-1: residual tumor diameter<2.5mm.
during operation
Incidence rate of adverse events
Time Frame: Baseline before any treatment,3 months after any treatment
According to NCI CTCAE v5.0
Baseline before any treatment,3 months after any treatment
